Chaoyang Investigation Bureau!
Technicians, after getting the suspect's video, immediately repaired and identified the picture.
Almost an hour later, they contacted Sun Changming.
"Chief, after we repaired the appearance of the suspect, we compared it with the criminal database.
But the match didn't complete! "
Sun Changming frowned:
"That is, the suspect has no previous convictions?!"
"That's right!"
The technician continued:
"Next, we have two ideas.
One is to obtain the facial scan data of passengers at Dajing bus station, train station, airport station, etc. and compare it.
This requires your approval!
And then again!
You can send several squads to investigate where suspects may haunt.
What do you think? "
"No problem, I'll arrange it!"
After Sun Changming finished the relevant matters, he immediately contacted the High Court and asked him to wait a little longer.
Inside the Hall of Personality!
Guan Hongyu was surprised:
"Well, with the suspect's photo and confirming her identity, why is it so difficult?
According to 253, the suspect must have applied for an ID card, and there should be a photo in the corresponding system.
The images of the suspect outside the concert venue are entered into the system for comparison.
Isn't it possible to directly confirm your identity? "
"Nope!
Dude, you take this for granted! "
The White Night God probed Guan Hongfeng, looked at Guan Hongyu, and explained:
"The core of the approach you're talking about is facial recognition.
In many film and television dramas, as long as the investigator has a person's appearance photo, he can perform facial recognition on the computer, through monitoring, identity systems, etc., to lock the location and identity of the target.
This actually exaggerates the power of facial recognition!
The principle of facial recognition is that each person's facial features are specific enough!
The principle of fingerprint recognition and DNA determination is actually the same.
The core of this type of identification technique naturally means recording and comparing this specificity.
This is not something that can be done by simply looking at it with the naked eye or scanning it casually by a machine.
Let's just say facial recognition!
We now have photos of the suspect from multiple angles, and by summarizing these photos, we can basically grasp the specificity of her appearance.
But the problem is!
For a number of reasons, even fingerprints and DNA have not established a complete citizen database, only criminals, missing persons and other special persons have established a database.
Facial features, let alone a corresponding database.
As for what you said, brother, the photos in the citizen ID card system are not very useful.
Because to fully express a person's facial features, not only do you need photos from multiple angles, but you also need to identify many feature points in your appearance.
This is not available in the ID card system.
Let's be honest!
Even if the technician requests the facial scan information at the bus station and other places, in many cases, it is not enough to match it. "
"That's right!"
Guan Hongyu abruptly:
"I thought it would be easy to get a photo of a person and confirm their identity!"
Black Cat Sheriff:
"For the most part, it's really simple.
For example, posting photos of suspects on the Internet, I believe that you will get clues soon.
But the other party is a murderer after all, and a serial killer.
We must avoid scaring snakes and dogs jumping off the wall.
When there is no way, it is easy not to post the bounty directly. "
Feng Yuxiu was obviously impatient:
"So what now?
Passenger data at stations and airports may not be valid.
Even if it works, the suspect may not have been to these places.
(CGAA) Investigating places where suspects may haunt is time-consuming and laborious.
That is to say, in a short period of time, it may not really be possible to confirm the identity of the suspect and complete the arrest? "
"It's not so pessimistic!
With the suspect's video data, it is equivalent to mastering Wang Fried.
Arresting him is just a problem! (Read violent novels, just go to Feilu Fiction Network!) ）
Of course, the specific search for a way should indeed be carefully considered. "
Gao Ting thought for a while:
"From what we had before, the results of the criminal profile of the murderer.
The murderer's temperament, preferences, etc., may all be weird.
This can lead to her being very withdrawn and isolated!
But even if you live in isolation, the basic needs of food, clothing, housing and transportation must be there.
Among them, the most indispensable is food! "
The High Court said, and Holmes added:
"And the murderer's economic situation should be average, at least without independent income."
Because we analyzed it before, judging by the method of dissection of the murderer!
She is either a medical nurse in her studies!
Or have dropped out of school!
In both cases, it means that she does not have a fixed job.
Ordering takeout or restaurants every day is unlikely.
If she was studying in medicine and the canteen, it is also unlikely.
Because according to the requirements of refining zombies, she needs to go to that crow mountain from time to time and sprinkle quicklime, crow blood and so on.
It was therefore impossible for her to be in school all the time.
I even suspect that she may not live on campus.
Because Deng Ling temporarily escaped the control of the murderer, it means that the murderer has a foothold in the mountains and forests west of the moat.
Therefore!
Even if the murderer is a medical student, he needs to solve the problem of eating and drinking from time to time near the upstream of Deng Ling's falling point.
She either goes to a cheap little restaurant!
Or buy your own food and cook!
If the murderer dropped out of school, it would be simpler!
The probability of her buying her own vegetables to cook is a little higher! "
Hannibal nodded:
"Therefore, to locate the murderer, it is best to search the surveillance near Deng Ling's falling water, vegetable market or supermarket."
There are also cheap small restaurants that are also worth investigating! "
Riddler:
"The murderer is estimated to have no car, monitoring near the bus stop, you can also search it!"
......
During the discussion of personality, the idea of investigation quickly took shape.
Gaoting immediately extracted the monitoring of vegetable markets, supermarkets and other places in specific areas and shared them for everyone to see.
He originally thought that the search time would be relatively long.
But less than half an hour later, Di Renjie, who had always been steady, suddenly spoke excitedly:
"Found it!
I seem to have found the murderer!
Everyone look at this meat buyer, is it a suspect? "。
